Hi, I am evaluating several DSPs for a multimedia application, such as DaVinci (Texas Instruments), Nexperia(NXP), Blackfin (Analog Devices) an so on. I have noticed that some DSPs belonged to TI have a VICP (Video & Image coprocessor) which is like a "black box" for programmers and it is only available for Third Parties of TI: (1) Is this right? What are the limits for using that coproc...

My hint would be to have a serious look into "autoconf", which will help you to figure out which types to use on the target platform. You're of course right by saying that an int need not to be 32 bit. (In fact, it

Hi. I just graduated in December with a B.S. in Electrical Engineering from a prominent Southern California university. For privacy's sake, I won't disclose its name but I will say that its mascot rhymes with "shoo-ins". Anyway, while I was there I took classes on a lot of different topics but the ones I enjoyed the most were the ones on signal processing (DSP, signals and systems, image proces...

Occasionally, I attend seminars re applied math, typically discussing filters, or image processing, often involving high dimensional spaces. The focus is usually the efficiency of the algorithms, or their accuracy, e.g. voice recognition. Of course they also try to prove theoretical correctness. And there's the problem, in my view. They throw around gradients and conjugate gradi...

Hello, I have the following setup: x[n] ----[ D/C ]----[ H(s) ]-----z(t)-----[ C/D ] ----- z[n] Basically H(s) describes a practical DAC (zero-order-hold+Reconstruction filter) but could later contain up/downconversion including its image rejection filters, cables etc. One can write the equivalent discrete-time system (sample time for both systems Ts): x[n] ----[ H(z) ]------ z[n...

I am having trouble understanding the meaning of an operation that a customer finds useful. They have a 2D block of data that is part of a medical image. They do a 2D wavelet transform on this, followed by a 2D FFT of the wavelet coefficient set. I find it hard to visualize what the result of this means. Any sugestions would be welcome. Thanks, Chris ==========================...

Since an image is word ten thousand words, here's what sums up what i'm trying to do http://www.geocities.com/michel0528/correlation.jpg As you can see, I'm trying to correlate the first signal by the second by correlation. The problem is, I didn't really expect the result you can see on the picture, I expected more something looking like from not too close like a delta function right in th...

Hi Group, I know my question may sound stupid. But I can not come up with a solution. So I post it here with the hope that someone could shed me some light. Thanks in advance! I am working on some image processing with FFT. It requires that the function to be FFTed into spatial frequency space. However, I found out that the result of FFT depends on the number of segments I choose. For e...

Hi, I am using the FFTW library to do some image processing. I am using the r2c plan to get the fourier transform. The documentation clearly states that the size of the output for a m*n input is m*(n/2+1). Also, the dc component of the result is the (0,0) element, rather than at the centre of the array. So what i need to know is, 1) How is the rest of the fourier transform oriented? 2) Wh...

If I transform the image to bessel space before calculate it's derivative: x = -10:10; T = besseli(x,s,1); im = imfilter(im,T'*T,'symmetric','same','corr'); Can it(bessel filter) surpress the noise introduced by derivative filters?

Hi I have developped an application for image inpainting. Now I want to claim that it can be used for realtime purposes. Does somebody know a paper which gives some boundaries for realtime applications? I want to refer to a paper to prove my assumption.

Using Code Composer V2.2 how do I configure the linker to generate code that starts executing at the EHPI execution start address of 0x10000 ? Is there a better utility out there for generating a more compact image than the TI supplied hex55? I have tried coff2bin, it only seems to cope with one section name at a time. Thanks in advance for any help.

Hi Community! I've got a problem that has been driving me mad for several days: I need a quick 2d convolution of a picture and a big (say 70x70) kernel. I was thinking of doing it in frequency domain using FFTW (the programme is in C++). This is the way I am doing it: 1. Pad the filter to the size of the input image. (padding "all around", so the "important" part is in the middle) 2....

Hi, Can anybody point me in the direction of a decent 'stereo expansion' algorithm (by this I mean the sort of thing commonly found in e.g. TVs, that makes a normal stereo image sound wider than it actually is)? Thanks, Jesper
